Mozilla has already crippled Firefox's extension system, so why bother?

What's preventing Mozilla from shipping it as an extension?

Are there any forks of Firefox with these add on limitations removed?

Any plans to support FireFox extensions?

firefox now requires developers to 'sign' their extension with mozilla, and has disabled the ability to side load extensions manually for more than just temporary use, unless you are using some special developer version of firefox. chromium still allows users to side load their extension. it's ironic that google would allow more freedom to the user than mozilla.

Once upon a time, Firefox used to do that for extensions.

Does it remove the change they made in Firefox 37-42 where you can't run or edit any add-ons/extensions without approval from Mozilla?

Was that before or after Mozilla decided to stop let you load proper add-ons, and make you settle for the crippled WebExtensions API?

uBlock Origin and DOZEN of other extensions!!No others allowed.Unless you use a beta version and do a weird thing with accounts and a website.And it's been broken this way for years now.Firefox seems to be trying hard to keep their benefits over chrome as minimal as possible.

It used to let you all extenstions, before mozilla went full google and crippled it.
